A toroidal vortex ring is formed when a fast moving fluid moves through a relatively still other or different fluid. For example, smoke rings blown through air, or bubble rings in water.
In our cannon example, to start with, the smoke is basically a fast moving ball. As it emerges through the opening, the smoke outside of the ball is being slowed down because of the friction between it and the edges of the hole. Once it leaves the cannon, there is friction at the interface between the smoke and the air in the room. The smoke in the centre of the ball is moving faster than the smoke around the edges, so the smoke on the edges starts to curl around and form a mushroom cloud. As the smoke reaches the back of the cloud, it’s drawn into the faster moving current of air in the centre. It’s this flow pattern that eventually causes the ring to form.

If you're underwater it's easy to make air vortex rings that rise vertically, but a lot harder to make ones that travel horizontally, because of the different water pressures at top and bottom, I assume. You can also make two horizontal air rings rotate in and out of each other, but that's a lot harder than making just one, and requires really calm water.
Yes! Vortex Science shows amazing properties. I would encourage anyone to look up Viktor Schauberger's work on Water vortexes. And nice rig by the way.
My professor Dustin Kleckner was a post doc at University of Chicago, who first created vortex knots in a lab setting
Hi Natasha,
Love this video 🙌🏼
I am a freediver and I have been making bubble rings anf and taking pictures with them for many years now...
I would love to hear your thoughts on bubble rings specifics (vertically in a water column) and if I can use some fluid dynamics knowledge to help me create something even better.
Thanks!
Bravo! Outstanding descriptions and demonstrations. Subscribed!
Cool video, can't wait to share this with my daughter
Vortex rings have been my obsession for the last couple years. Finally upgraded to a fog machine and a trash can with a hole in the bottom.
I’m here because I was looking up the science behind mushroom clouds (mainly nuclear but it’s not just nukes that cause them) on Wikipedia.
If you look at videos of high altitude nukes, they actually form a ring (because they’re not pulling up material from the ground because it’s too high).
Awesome film. So pretty! Those little DIY air cannons are pretty east to make too!
really enjoyed this video
Great video and vortex cannon thanks for posting. Is there any more scientific information about these anywhere? like size of orifice vs velocity vs mass etc. I would like to work out an optimised version for long distances but can't really find out much information about them.
Make a fun and experiment. Physics girl has a good video on the subject. You can buy a cheap fog machine, or, I bought a couple of those “misters” that create water vapor. Put it in a container with water, cut a hole and start squeezing.
If the air is very still, the wingtip vortices from an aircraft can combine to give a line of rings. When I worked with superconductors, I wondered whether flux lines might do the same thing. In theory two opposed flux lines ought to annihilate each other. In practice they can't as there is nowhere to dump the energy fast enough. So you might get similar vortex rings in super electron wave functions, that slowly string as the energy gets dumped to the normal electrons.
good explanation easy to understand
Superb,best explained 👌👌👌👌
This is very cool! Best explanation ever!
Can I make one at home?
Sure!
Lots of tutorials online.
Nice video! One thing i'm wondering is that what if i make a hole shaped square or triangle? Would the smoke ball follow its shape?
Yes.
But it doesn’t stay that shape while it travels, it wobbles. Smarter everyday and physics girl have some good videos on the subject.
Instructions unclear... I now have lung cancer.
Hold up, i wanna hear about those dolphins doing that with their fins and blowing bubbles, thats crazy
They just swipe their fin. Ever see Vapers do “tricks”? If you have a bunch of fog an o flat surface, you can swipe your hand through it and create “tornados”. Look it up. Pretty fun.
They make the air rings out of their blowholes. There are videos online.
one of the most dangerous weapons ever made
ya man
Amazing video
i would be curious to rotate the ring horizontally. cause a vortex also turn around the center
we get it you vape
Bwahaha
It may be a weapon, a very very secret weapon of .... ( further post is classified )
plasma bluster.
loooooved your video! thank you.
Very cool. I’ve seen videos of dolphins making them and them swimming through them. Playing and entertaining themselves. It’s cute to watch.
"...and this handy bat that we keep in the prep room in case of emergencies"
So, what are they researching in there besides vortex rings? 😆
Bilbo would be proud.
Hold up.... This lady isn't just smart... But she's drop dead GORGEOUS!!!!!
Watching this while holding a blunt and blowing vortex rings.
What are you using for smoke
We used a smoke machine and smoke machine fluid.
But why does the smoke when it comes out of the smoke gun, why does it take on the form of a round mushroom-like shape before it visibly becomes a torus?
Because when it first comes out of the hole, the pressure is relatively equal. You gotta think like a raindrop here. It starts round, and flattens and eventually splits of it gets too big. That’s essentially what’s happening here.
I knew it!, Dolphins are taking over the World!🐬👀
I've been saying that for years finally someone gets it 😂
rain drops falling on a puddle, underwater bubbles accelerating towards the air :000
Now imagine this in the "vacuum of space" - there you go, particles.
...now try something mathematically interesting: add vanes around the exhaust exit to give the ring chiral spin (helical-flow cf the direction of your fingers curled behind your thumb)...
just amazing
Love from India 🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳
I keep waiting for her to present 'Needle'
those videos are beautiful
Time to educate installing correction @ 3:47-3:58 { a rain drop is not going to produce the kind of vortex pattern as the eye dropper experiment , the drop falling from sky dose not have a tube with surfaces to apply resistance in order to incite rotation, the pattern from a drop falling from the sky is more like an explosion.} in the experiment the vortex ring was incited at the droplets exit from the the eye dropper.
The vortex ring is created by differential drag as the droplet enters the liquid, it isn't a result of the dropper tube. You can tell this quite easily because there is some distance between the dropper tube and the surface of the water, and the droplets aren't in the shape of rings while falling, only after they enter the still liquid below.
Droplets are still quite circular in the first place, also its not from the shape its from the friction of two different liquids or gasses. Maybe its time to educate yourself smart guy. I love the confidence though lmao.
How can i make the underwater one?
the problem is to generate sucha amount of smoke at home without spending too much money and/or effort
Incense, fireworks, dry ice in water. Anything that forms a visible vapor works.
Amazon has cheap atomizers, marketed as “misters” for ponds and humidifiers. I bought a couple, they’re messy (they splash) but once you get that under control, they are so much fun to play with the fog making tornados and tons of rings.
Now I know how to make a smoke ring. How do I make a smoke ship??

why does diameter increase?
Due to the direction of the spin, the pressure on the outside is lower, on the inside part of the ring, the pressure is higher, and that expands it. Physics Girl has some good videos on the subject that go into that subject.

You don’t suppose I could propose to you with a smoke ring? 😉💍
I know that was a little swift so maybe we can check the ratio of our inertial forces to that of viscous forces and see if we can achieve laminar flow. Oh who needs Reynolds number, I just want your number, ma’am.😂
thanks for this

That's epic.
Can the vortex stop crimes?
at 1:59 the reaction! XD
€20 k for the guy or girl who films himself or herself farting vortex rings.
Lady lady lady..thank you my lady 😊😘
My class did this but I’m in quraintine so my mum showed me
Why can nobody spell quarantine?
shawty blowing some fat rings, respect.
It be cool to try this with a magnetic field
the doctor has been located
Could Vortex Rings explain solar dynamics?
So how much money dose she get paid to blow smoke?
more than you

good topic. u r beautiful
but what attracts the smoke to itself?
the reason i ask is I was wondering about clouds, you have a big cumulonimbus and all around blue skies, there has to be an attracting force but at the same time a repelling force or we could not have indervidual snow flakes for example
Cumulonimbus clouds build up around updraft vortexes that create temperature-moisture gradients that, as a result, form into their own sort of contained systems. Once the thing gets started, it draws in more stuff that feeds it until it "blows up" in rain, hail, and lightning storms driven by its own contained ionic forces.
It's like, once a process starts, it sucks in more of what makes that process work, and then it runs the process until it reaches a climax or tipping point. In a way, this is similar to how gravity "clouds" form galaxies and star systems then fling them out as coherent units of mass.
Likewise, a hurricane or the Great Red Spot of jupiter get themselves spinning and the spin itself becomes the driving force that sustains itself. In such cases, there is either an external greater source of energy or a conservation of angular momentum that drives these subsystems. Otherwise, like the basic smoke ring, their boundaries spread out and dissipate from friction.
Raindrops, snowflakes, hail stones, individual star systems and so on at various scales are the result of the vortex drawing in enough energy or material that the ingredients themselves go through a transformation and change how they interact with that system. Often they drop or fling out of the vortex once they achieve enough concentration or energy, or they disperse en masse when the vortex itself loses coherence because of the amount of transformations.
The influence of a process forms a structure. The structure then runs on the influences of its own process. This process of the structure creates new structures. The new structures then act according to their changed natures. This is the story of rains and stars :)
Differences in temperature, moisture, and the friction talked about keep it together. The O shape gives it a platform to wrap around as the friction on the edges pushes it back but also slightly inwards near the back of the O. The smoke or vape will be denser than the air around it so until the vape/smoke thins out it cannot mix very well with air.
@@animistchannel2983 what an epic response.
What about when you do it with your mouth 🤨
Same exact thing
Het is net een koprol maar dat is het niet...let op ''het is net'' .
1st comment 😛
Politically correct female presenter, inevitable pointless music and gesticulation.
"бог" - это Ад и Рай вмести.
"богом" мы называем диапазон частот, от полного поглощения/разрушения энергии/материи, до полного излучения/созидания энергии/материии:
(☠️...-\0(1)/+...🌱) - ТОР♻️, вечный цикл Жизни, это и есть "бог" или Разум, другими словами.
Отсюда и возникла настоящая ТОРА и карты Таро, кстати.
Можно сказать, что "бог" - это любовь к ненависти и ненависть к любви, ОДНОВРЕМЕННО.
"Ионы" или "фотоны"(вы ведь эти названия просто так придумывете от болды, так что разницы нет) - это энергия излучаемая Тора_ми, этой энергией пронизано всё, это та-самая "прана" и есть и сами торы это таже самая энергия, закрученная в виде торов♻️⚡. А искусственно, это излучение можно сделать с помощью высокого напряжения, высокой частоты, тоесть повышающей катушкой ("Теслы", хотя она не его вообще) или простым бытовым ион_и_за_тор_ом, в котором внутри тоже эта катушка стоит, просто в красивом корпусе. И собирать её можно из радио-Эфира также, только в обратную сторону надо всё делать, подключить наоборот просто, так чтобы," корона" была приёмником.. 👑⚡⬇️🙃
Все "боги" - это эти Торы. Планеты все, во всех Галактиках - это Торы, их и назыают "богами".
А вся Вселенная, котороая вообще ВСЯ - это Тор-Торов просто или фрактал, другим словом, фрактальный узор, это и есть, линии энергий и полей в этих торах и их сплетения и "числа Фибоначчи", это тоже, тоже-самое и любой язык, математика, физика, химия, музыка и тд - это тоже, тоже самое, это всё эти Торы♻️...
И наши тор_сы - это торы, чакры - это тор_ы, атомы - это торы, моторы-это намотанные торы, эква_тор и тд и тп, а Земля и др Планеты - это Си(век_торы) _муля(ж) _тор, тоесть оцифрованный аналоговый Мир или проще говоря - школа Душ☝️🧠👁️
Нет ничего больше, кроме них💥🤷
Внутри у этих торов, есть тонели-воронки, или порт_алы и внутри них, можно перемещаться по всему пространству Вселенной, это и есть, настоящие "космические корабли" или "летающие тарелки", тоесть, есть технические средства передвижения, которые управляются торсионным полем пилота этих кораблей, он и есть двигатель и центр управления в них... Только так, можно папасть из одной Галактики в другую, без времени, так-как внутри тора, времени нет и гравитации нет... . ☝️🧠👁️💥
"Люцифер" - это любитель цифр, тоесть логический Ум или левое полушарие мозга, или Логос, или "Дьявол", это синонимы. В радиоэлектронике, это называется, "АЦП" - аналого-цифровой преобразователь. Наши(чьи угодно) мозги, это и есть Торы, а точнее ре_зона_торы или ЦАП/АЦП(в обе стороны работают они, как из аналогового сигнала, делают цифровой, так и из цифрового, делают аналоговый, одновременно⬅️🧠➡️...
Ютуб, тоесть метавселенная, которую сейчас создают иудеи(демоны=дьяволы=люциферы и тд воплоти) и в которой Мы все погрязли уже целиком, это и есть Ад, во власти "Люцифера", тоесть иллюзия рая, построенная на нашей энергии жизни и смерти☝️🧠👁️👹🔥❗❗❗🐑☠️👇🤦
А "Сатан_а" - это интеллект, тоесть цикл мыслей в логическом уме(левом полушарии и физ теле и физмире вцелом, все циклы)♻️
Разумный сомодостаточный Человек(хозяин Земли и её ресурсов, объедигяющий Свет Солнца и Тьму Земли в себе), это и есть Тор, то-есть Бог воплоти☝️😇
Ад- это тело, сделанное из Земли, которое есть землю, живёт в домах из земли, все вещи делает из земли, весь физ мир из земли сделан, это и есть Тьма и она боится смерти постоянно.
В Римской Империи , олицитворение Тьмы - это иудеи(евреи), которые и правят Римом, кверногами, они-земля(матения, отрицающая свою материалтность🙃🐑🤦тоесть, антиматерия и антиэнергия, разрушители, паразиты), мнят себя главнее Света(=Солнца=Души=энергиии), они и рвут мозги всем людям напополам буквально, переворачивая Истину, превращая её в ложь, а ложь назыаают "истиной", это хуцпа, по принципу: " разделяй мозги гоям и властвуй над ними вечно", "выбор без выбора", "все пути ведут в Рим", "свобода - это рабство", "война - это мир" и тд и тп, НЛП и пропаганда - это и есть их "чёрная магия", а фиатная валюта - это и есть эквивалент жизней всех их рабов-гоев(нас всех, без исключения), тоесть энергия+время жизни раба=трудочасы=жизнь🐑♻️☠️🇻🇦🇮🇱👹🩸⚡
